NOTE: It has been discovered that the MicroSoft Word Version fluctuates characters: many of the simplified characters come out as traditional characters. This does not happen with the PDF files however. So if you want to make sure you have simplified characters, use the PDF files rather than the MicroSoft Word files. A simple test to see if your computer is operating the MS Word simplified characters correctly, can be done on the word " shenme " - " what ". The " me " in traditional is complex; but easy using simplified. Simply compare " shenme " with how it looks in MS Word and PDF. If they are the same, your MS Word is showing Simplified Characters correctly. If different, you may wish to stick with just the PDF files ...
